Authorities rounded up about 11 dogs Monday and returned to the area Tuesday to find four more spotted by a deputy.

Authorities say it appears the pack of wild dogs attacked Sherry Schweder as she walked a dirt road near her house. They say it appears her husband later went looking for her and was also attacked by the dogs.

The Humane Society says federal statistics show an average of 16 people die each year from dog bites.
